A while ago there was an issue with the Nexdome driver loosing connection to the shutter as soon as the shutter reached the top "open" magnet. But that was resolved.
At least it was in Stellarmate.
Today I decided to try the Mac OSX version of KStars, and downloaded the latest version. Now the shutter disconnect issue is back!
I didn't even notice it until I tried to quickly shut the shutter when high winds started. I tried for 10-15 minutes to try and get the shutter to reconnect with no luck.
I had to close the shutter manually.
This is the same issue e had before with the Linux/Pi version of KStars. Is the Mac version of the Nexdome driver older?
